Description

Technical Field

[0001] This utility model relates to the technical field of galvanizing line cleaning equipment, and more specifically, to a device for the secondary utilization of rinsing and desalination water. Background Technology

[0002] Currently, galvanizing line cleaning systems consist of alkaline washing and rinsing processes. The strip is first rinsed with alkaline solution, then cleaned with desalinated water to prevent alkaline residue. As rinsing time increases, the alkaline concentration in the desalinated water gradually rises, affecting the cleaning effect. At this point, the desalinated water in the rinsing tank is replaced, and the replaced water is directly discharged into a wastewater pit for treatment. This direct discharge not only causes a serious waste of water resources but also increases the consumption of desalinated water and the cost and pressure of subsequent wastewater treatment, significantly increasing production costs. Therefore, this paper studies and improves the existing structure to provide a secondary utilization device for the rinsing and desalination water, aiming to achieve a more practical purpose. Utility Model Content

[0003] 1. Technical problems to be solved To address the problems existing in the prior art, the purpose of this utility model is to provide a device for the secondary utilization of rinsing and desalination water. It can achieve the optimized allocation of water resources through secondary recycling of the desalinated water after rinsing, improve the economy and environmental protection of the overall production process, effectively solve the problem of water waste caused by the direct discharge of rinsing and desalination water in the galvanizing line cleaning process, and at the same time reduce the amount of desalinated water used and the cost of subsequent wastewater treatment.

[0004] 2. Technical Solution To solve the above problems, the present invention adopts the following technical solution.

[0005] A secondary utilization device for rinsing and desalination water includes a rinsing tank, an alkali solution preparation tank, an alkali solution tank, and a wastewater pit. One end of the rinsing tank has an overflow port, which is connected to the wastewater pit via a guide pipe. The guide pipe is connected to the alkali solution preparation tank via a guide pipe. One end of the alkali solution tank is equipped with a pneumatic pump, whose inlet and outlet ends are connected to the alkali solution tank and the alkali solution preparation tank, respectively. A level gauge is installed inside the rinsing tank, and a level gauge and a conductivity meter are installed inside the alkali solution preparation tank.

[0006] Furthermore, the other end of the rinsing tank is fixed to the top and connected to a desalination water supply pipe.

[0007] Furthermore, a solenoid valve is installed on the first guide pipe, and the solenoid valve is located below the connection between the first guide pipe and the second guide pipe.

[0008] Furthermore, a solenoid valve is installed on the second guide pipe.

[0009] Furthermore, the inlet end of the pneumatic pump is connected to the inside of the alkali tank through guide pipe three, and the outlet end of the pneumatic pump is connected to the inside of the alkali mixing tank through guide pipe four.

[0010] Furthermore, a height difference of m is provided between the rinsing tank and the alkali solution preparation tank.

[0011] Furthermore, the level gauge one and level gauge two are respectively fixed to the inner walls of the rinsing tank and the alkali solution preparation tank by brackets.

[0012] 3. Beneficial Effects Compared with existing technologies, the advantages of this utility model are: This solution, through reasonable pipeline design and automated control, diverts and recycles rinsing water reaching a certain concentration in the rinsing tank, allowing it to be reused in the alkali solution preparation process. This achieves water resource recycling and reduces the company's energy consumption and environmental protection investment. In actual operation, when the liquid level in the rinsing tank reaches the threshold set by level gauge one, some rinsing water enters the alkali solution preparation tank through guide pipe two. Simultaneously, a pneumatic pump automatically replenishes alkali solution in the preparation tank based on the conductivity value detected by the conductivity meter, ensuring the prepared solution concentration meets process requirements. Excess rinsing water is directly discharged into the wastewater pit through guide pipe one. The entire process requires no manual intervention and is stable and reliable. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Example: Please see Figures 1-4 The rinsing and demineralized water secondary utilization device includes a rinsing tank 1, an alkali solution preparation tank 2, an alkali solution tank 3, and a wastewater pit 4. One end of the rinsing tank 1 is provided with an overflow port 5. The overflow port 5 is connected to the wastewater pit 4 through a guide pipe 6. The guide pipe 6 is connected to the alkali solution preparation tank 2 through a guide pipe 7. One end of the alkali solution tank 3 is equipped with a pneumatic pump 8. The inlet and outlet of the pneumatic pump 8 are connected to the alkali solution tank 3 and the alkali solution preparation tank 2, respectively. The rinsing tank 1 is equipped with a level gauge 9. The alkali solution preparation tank 2 is equipped with a level gauge 10 and a conductivity meter 11.

[0017] See Figure 2 The other end of the rinsing tank 1 is fixed at the top and connected to a desalination water supply pipe 12.

[0018] See Figure 2 A solenoid valve 13 is installed on the first guide pipe 6. The solenoid valve 13 is located below the connection between the first guide pipe 6 and the second guide pipe 7. A solenoid valve 24 is installed on the second guide pipe 7. In use, the setting of solenoid valve 13 and solenoid valve 24 can facilitate the control of the overflow water flow direction in the first guide pipe 6 and the second guide pipe 7.

[0019] See Figure 4 The inlet of the pneumatic pump 8 is connected to the inside of the alkali tank 3 through the guide pipe 15, and the outlet of the pneumatic pump 8 is connected to the inside of the alkali preparation tank 2 through the guide pipe 16.

[0020] See Figure 2 There is a 10m height difference between the rinsing tank 1 and the alkali solution preparation tank 2. When in use, the terrain conditions of the 10m height difference between the rinsing tank 1 and the alkali solution preparation tank 2 allow excess water in the rinsing tank 1 to flow out from the overflow port 5 and be automatically introduced into the wastewater pit 4 or the alkali solution preparation tank 2 by gravity and under the action of the guide pipe 6.

[0021] See Figure 3 and Figure 4 Level gauge 9 and level gauge 10 are fixed to the inner walls of rinsing tank 1 and alkali solution preparation tank 2 respectively by brackets.

[0022] When in use: When the alkaline solution in the rinsing tank 1 does not meet the production requirements, the desalination water supply pipeline 12 replenishes the rinsing tank 1 with water. The liquid level is controlled by the level gauge 9. As the water level rises, excess water will flow out from the overflow port 5.

[0023] At this point, there are two scenarios. First, when the data displayed by the level gauge 10 and conductivity meter 11 inside the alkali solution mixing tank 2 meet the production conditions and no additional water is needed, the solenoid valve 13 opens and the solenoid valve 24 closes, and the overflow water flows directly into the wastewater pit 4.

[0024] The second method: When the liquid level in the alkali solution preparation tank 2 is low and water needs to be added, close solenoid valve 13 and open solenoid valve 24 to allow overflow water to flow into the alkali solution preparation tank 2. Simultaneously, monitor the liquid level using level gauge 20. As the overflow water flows in, the conductivity inside the alkali solution preparation tank 2 will decrease. At this point, turn on the pneumatic pump 8 to transfer the alkali solution from alkali tank 3 into the alkali solution preparation tank 2. Observe the conductivity meter 11 until a solution meeting the requirements is obtained. Through reasonable pipeline design and automated control, the rinsing water reaching a certain concentration in the rinsing tank 1 is diverted and recycled, allowing it to be reused in the alkali solution preparation process. This achieves water resource recycling, reducing the company's production energy consumption and environmental protection investment.
